gi MA-w MM! Patented Oct.13, 1931 PATENT OFFICE JOHN WILLIAM NASMITH, OFHEATON MERSEY, MANCHESTER, ENGLAND COMBING MACHINE FOR TEXTILE FIBERS Application filed December 11, 1929, Serial 1%. 413,341, and in Great Britain August 13, 1929.

The invention relates to rollers in combing machines for textile fibers, of the Heilmann type.

In combing machines of the type to which I have referred the leather detaching rollers of say six different'combing heads are usually lifted from and lowered upon the combing cylinder segment by means of a shaft oscillating around its longitudinal axis, a lever at each combing head being carried upon the shaft and itself carrying the leather detaching, roller bearings. The rollers and their weights are liable to cause torque in such shaft, with resultant unevenness of tim- 5 ing in the detaching, and, to obviate this, extra shaft-oscillating means have been provided along the shaft.

The object of the present invention is a means whereby a shaft may be operated to lift any desired number of detaching rollers distributed along its length, the possibility of torque in the shaft being entirely eliminated.

According to the invention and with this object in view the weight to be lifted is carried upon a fulcrumed lever or fulcrumed bars, and a rod is provided which is movable in the direction of its length, with parts interposed between the said rod and the plurality of levers to lift or lower the latter, andtheir borne weights, according to the direction in which the rod is moved.

The interposed parts may be fulcrumed bell crank levers which, on longitudinal 3 movement of the rod, lift or lower as the case may be a bar which in turn lifts the ends of the roller-bearing levers.

To adjust the timing of the lift, the bar just referred to may be made adjustable as 9 to its surface, as by adjustable screws borne on the said surface which screws make contact with the lever ends to be lifted.

Each lever for each weight may be a threearmed lever, the end of one arm thereof serving as the fulcrum point, the second arm bearing the roller, and the end of the third arm taking the thrust of the bar referred to above.

The invention as applied to a combing machine for the lifting of a plurality of leather covered detaching rollers will now be fully described, with suitable constructional detail-s as above set forth. Reference will be had to the drawings hereto annexed, in which Figure 1 is an elevation of one detaching roller and the lifting means, with the operating rod and accessories, and Figure 2 is a view at right angles to that of Figure 1.

Referring to the figures a rod 3 is provided slidably fitted in suitable bearings of The other arm of each such lever 4 carries a further anti-friction bowl 7 which makes contact with a bar 8, fitted in suitable bearings which allow vertical movement thereof, the said bar being parallel to the rod 3; and on the upper face of such bar are fitted in tapped holes, adjustable screws 9 with nuts 10 At each combing head is fulcrumed a threearmed lever one arm 11 of which is fulcrumed upon a shaft 12. A vertical arm 13 bears at its upper extremity bearings for a detaching roller 14; and the third arm 15 of the said lever is provided with an anti-friction bowl 16 which rests upon one of the adjustable screws 9 upon the bar 8. Two levers are employed as shown to support the bearings for a roller 14.

The weighting of a roller may be effected by means of springs 17 or by any suitable weight, acting upon a lever 18 which is as to form and construction, identical with the other three-armed lever and is bifurcated to fit upon the shaft 12.

Where a lever arm is bifurcated for fulcrumming as shown-a convenient construction for fitting and removal-a stop such as shown in Figure 2 is provided, this stop consisting of'an adjustable screw 19 threaded through a tapped projection 20 on the machine framinga As shown, this stop contacts with the weighting lever 18, and prevents loose movement thereof onits fulcrum point as it descends.
